9 Claims.

This invention relates to improvements in ven-'- tilator panels for windows. Such panels are fitted into window frames below the lower sashes, for

example, and have an opening therein communieating with the outer air to permit ventilation through said opening when the window in other respects is closed. Among other uses said opening may constitute the intake for a duct leading to a power ventilator of the semi-portable type used in homes, ofiices, churches, schools and other buildings.

It is an object of the invention to provide a ventilator panel which is simple and easy to install in any type of double hung window and which can be adjusted readily in any width of window frame and make a suificiently tight fit therein to prevent substantial leakage of air around the same.

It is another object of the invention to provide a device of this character which is inconspicuous,

whichdoes not require the driving of any nails or screws into the window casing, or which does not require the defacing of the casing in any way and which can be taken from the window and moved to another window in the same room or in another room either in the same building or in another building without damage and without requiring renewal of parts.

Further objects will become apparent as the description is read in connection with the accomp'anying drawings in which one embodiment of the invention is illustrated.

Fig. 12 is a section on a horizontal plane of another detail.

The panel in its commercial form consists of three sections fitted together between the window sill and lower sash rail of a double hung window 55 and partially overlapping the inner vertical surface of said sash rail. It comprises a central section or duct connector section 11, and two end sections 12 and 13. Filler sections may be used if these are necessary. All these sections, when installed in a window or other opening are mitered together in abutting end-to-end relation to form an apparently continuous interior facing as shown in Fig. 1.

The duct connector section 11 is made of a shallow channel or other suitably shaped section 14, this shallow channel also being typical of the end and other filler sections. The legs 15 and 16 of the channel point outward (out of the window) so that the plane vertical surface of the convex side of the channel is the one seen by the occupants of the room. The bottom leg 16 rests on the window sill 1'1. The outer edge of the bottom leg 16 is bent downwardly as'shown at 18 and rests against the outer vertical edge of said $111 to prevent inward movement and also to make a good seal. Sash 19 closes down adjacent the edge of upper leg 15 and is prevented from scraping against this edge by means of a strip of felt 20 or other yielding or resilient material which prevents substantial leakage of air and furthermore provides a dust proof and sound proof joint. This resilient material is mounted in the slot formed by upper leg 21 of channel 22 mounted slightly beneath leg 15, the two channels 22 and 14 being held together by welding or otherwise fastening the same. See Fig. 7. Leg 21 preferably should be slightly shorter than leg 15. The lower leg 23 of channel 22, which runs the entire length of duct connector section 11 and extends slightly beyond both ends thereof, also acts as a stop for 90 sash 19 and prevents lowering the same too far. Channel 22 also stiflens channel 14. Adjustable guides 24 for sash 19 preferably are provided as shown, one at each end of section 11. Said guides are adjustable to the thickness of the lower sash rail having slots therein through which pass screws 25 mounted in plate 26.

The'duct connector section 11 has an opening 27 in it with a suitable frame 28 for making a connection with the intake duct of a ventilator hereinafter referred to. A visor 29 attached to lower leg 23 of channel 22 (Figs. 2 and 8) is also provided over opening 2'7 so that rain and snow do not enter it. A mortise 30 (Fig. 8) is provided at the lower part of each of the two ends of the concave side of the channel 14 to make connection with the tenon of the adjoining end section or filler section if it is needed. Said mortise is formed by welding steel strip 31 in place as shown, spaced from the back of the channel to leave opening 30. The tenon is formed on the abutting channel section 12 or 13 by welding a short length of channel section 32 against the back thereof and which projects from the end thereof as shown in Fig.-5, so that it will fit snugly but slide easily in said opening 30.

The end sections 12 and 13, having adjustable telescoping end pieces are made right and left hand respectively so that they may be used at opposite ends of the duct connector section 11. Therefore only one section will be described as both are alike in construction and action and furthermore one adjustable end section is sufficient for practical purposes, although two are preferable. The facing (Fig. 10) is a shallow channel 33 of the same height and contour aschannel 14 used in duct connector section 11 and against which it abuts. It has upper leg 34 and lower leg 35 with dependent portion 36. A number of such channels are provided varying in length by one inch increments so that by proper selection any width of window may be fitted, the adjustable telescopic end piece hereinafter described being adapted to be extended to fill in any opening less than one inch long. A clip for a felt strip 3'7 is made by welding an angle 38 slightly below leg 34. The adjustable telescopic end piece comprises short channel section 39 at the end of section 12 opposite tenon 32. This end piece fits telescopically and slidably in the concave side of channel 33 (Figs. 5 and 9). A limited adjustment of the end piece with respect to channel 33 is permitted by slots 40 in channel 33 cooperating with screws 41 in channel 39. Said screws, when tightened, lock the adjustable end piece in place after proper adjustment is made.

When the composite panel is installed in a window, the approximately correct length is obtained by using end sections of such length that said panel may be fitted between the inner stop beads 42 of the window frame. The final fit is obtained by pulling out the adjustable end pieces until the vertical end of channel 39 abuts against the stop beads 42 (Fig. 12). Screws 41 are then tightened. I

Since the channel 39 fits telescopically in the concave side of section 33, the slight break in the continuous appearance is hardly noticeable at an end of the connector close to the window frame. An angle 43 extending the full width of channel 39 is welded to the concave side thereof, close to and parallel to the upper leg thereof to form a slot for holding a strip of felt 44 or other resilient material, as described in connection with the other portion of the section. The felt used is installed preferably after the window connector is installed and usually is made continuous across the entire connector instead of providing separate pieces for each section. It has been found unnecessary to support the felt where it spans the small gap left between-angles 38 and 43 (Fig. 5) resulting from the adjustment of the telescopic end piece. The felt strip contacting with the interior surface of the lower sash rail prevents leakage of air regardless of whether said sash rail is in its lowermost position against the stop which limits its downward movement, as shown in Fig. 2, or whether it is somewhat higher, as long as it is not raised high enough to clear said felt strip.

Channel 39, as shown in Figs. 3, 9 and 10, also has attached to it, at right angles to its outer end, an offset adjustable channel 45. This is of such size that the legs thereof fit into the sash groove 46 as shown in Figs. 2 and 12. Leg 4'7 0f adjustable channel 45 is formed by attaching an angle to the end of channel 39 or by forming it as a part of the end of the leg of angle 43 as shown. Although leg 47 is of the same length vertically as the balance of adjustable channel 45, the other portion of the angle at a right angle to leg 47, is preferably of the same height (top to bottom) as channel 39 (see Fig. 3). The base of the channel consists of overlapping plates 48, 48, the latter beingwelded to the angle 47. Plate 48 is bent to form the other leg 49 of said adjustable channel 45. These angles 47, 49 have their upper ends at the same level as plate 26 of guide 24 or lower leg 23 of channel 22 since the lower edge of sash 19 contacts with it. The slots 50 in the angular continuation 48 of leg 49 allow it to be slidably adjustable on screws 51 in web 48 so that channel 45 may be made of varying widths and leg 49 will abut against parting strip 52. When the end of channel 39 abuts against stop 42, the legs 47 and 49 of channel 45 enter sash groove 46 to thereby prevent lateral movement and securely hold the end of the window connector in place, after screws 41 and 51 are tightened. Since the legs of the adjustable channel 45 project into sash groove 46, it is necessary to have some end adjustment of said panel or it becomes impossible to install it properly without removing stop bead 42. Such adjustment is provided by the telescopic end portion heretofore described.

When only one adjustable end piece is employed, attached to the end of one of the end sections, the other end section has an adjustable channel attached directly thereto at right angles, similar to those previously described. Thus the length of the panel, as a whole, is varied by adjusting one end only, for the small amount necessary.

The end-to-end channel joints are sealed by the tenon 32 and the overlapping projecting ends of channel 22. Furthermore, the lower sash rail 19 closes down over the upper portion of the channel and tends to prevent the entrance of rain, snow, dust, dirt and noise through the vertical joints between the channel ends.

Filler sections may be used in addition to the duct connector and end sections. Such filler sections have the construction of that portion of the end section away from the telescopic end piece. They are tenoned at one end to make connection with the mortise of the duct connector section and mortised at the other to receive the tenon of the end section.

After the window connector is installed, the lower sash is open a certain amount so that an opening is left between the window pane 55 of the upper sash (Fig. 2) and the top rail 56 of the lower sash, and also between the Window pane of the lower sash and the lower rail of the top sash. This allows air and noise to enter. A seal is therefore provided to close one of these two openings, preferably the upper one. It consists of composite angle 57 made by welding two of the legs of two angles together as shown in Fig. 11, leaving a slot between the other two legs in which a piece of felt 58 or other resilient material is mounted and then held by pinching the legs together. On the top of the upper of said legs any suitable number of adjustable clamps 59 are mounted, as by welding. Each clamp consists of a steel sheet welded to angle 57 and having two of its edges 60 turned back on themselves as shown to form guides for a tongue 61, the projecting end 62 of which is turned down at right angles, to form one jaw of the clamp, as

shown in the drawings. A portion 63 of the metal is punched out of the other end and turned up at right angles, leaving a slot 64, an opening being provided in said turned up portion. An angle is welded to the sheet below tongue 61 and is disposedin the slot 64 as shown. Angle 65 has a threaded opening to register with said other opening in portion 63. A long screw 66 which may be a thumb screw or one with a screw driver slot, is in threaded engagement with both holes and when'turned causes slidable member 61 to be adjusted back and forth in its guides. The top rail of sash 56 is gripped between angle 57 and leg 62 of slidable member 61 as screw 66 draws the slidable member in. When the screw is tightened the seal is held firmly in place. Felt 58 is in contact with window pane 55 of the upper sash and provides a wind, dust and noise proof joint therewith. The construction shown also allows for a considerable variation in thickness of the top of sash 56. The construction is simple, effective and is hardly noticeable from the room, especially if the parts thereof are of the same finish as the sash. I

The frame 28 on the middle section of the panel is open at the bottom as shown in Figs. 2 and 8 and is arranged to fit over theflanged end 6'7 of duct 68 as shown also in Fig. 4. Thus before the panel is installed in the window it may be slipped down over said flanged end to lock the parts together and after said panel is installed in position, the window sill l7 prevents said duct from moving downwardly to disengage it from the side members of the frame or guides to which it is slidably fitted. The duct is preferably held in position slightly above the window sill to clear the same as for example by an angle iron 69 or other suitable support.

Although the ventilator panel is shown mounted in the lower part of the window frame, it may, under certain conditions ofuse, be mounted in the upper part thereof.
